While some people have naturally steady hands, many of us have a hard time taking clear photos, especially in low light. If you fall into the latter category, ditch the tripod and try building a chest support out of PVC pipe.
This DIY creation was originally designed for those with health problems that prevent them from taking steady shots, but let's be honest—some of us are just plain twitchy, and could benefit from this as well. All you need to build this chest support is a few small pieces of PVC pipe, a bolt, a nut, and something to function as the hinge on which your camera will sit (you can get creative with what you have lying around; the instructions use a piece of a hollow metal support beam). It's an extremely simple way to get steady shots when it counts, as long as you remember to breathe like a sniper (especially since it's sitting on your chest).
